precision
A number representing the number of digits to be printed for numbers printed with
the print(), printbuffer(), and printnumber() functions; must be a
number from 1 to 16; set to 0 to have the instrument select the precision
automatically based on the number that is being formatted
Details
This attribute specifies the precision (number of digits) for numeric data printed with the print(),
printbuffer(), and printnumber() functions. The format.asciiprecision attribute is only
used with the ASCII format. The precision value must be a number from 0 to 16.
Note that the precision is the number of significant digits printed. There is always one digit to the left
of the decimal point; be sure to include this digit when setting the precision.
Example
format.asciiprecision = 10
x = 2.54
printnumber(x)
format.asciiprecision = 3
printnumber(x)
Output:
2.540000000e+00
2.54e+00
